Search Party Feature
Search Party is a web browser extension which "socializes" web
searches, connecting people with ephemeral interests in particular
topics together. What people do with that connection is up to them, but
I imagine both strictly functional uses (sharing links to the most
pertinent web pages, disseminating non-web information related to the
topic, etc) and more sociable, entertainment oriented conversations
(say, arguing about the relative merits of a Corvette vs. a BMW M3).
